Type-bar mechanism



A. N. WODRUFF TYPE BAR MEGHANISI Filed March l, 1926 ATTORNEYS I 4tion are Simp direction against the platen. It is for this reason that the gear teeth 15 are arranged to form a surface eccentric with respect to the pivot of the't'ype bar as plainly shown in Figs. 1 and 2 so that in the initial portion ofits movement substantially greater power is applied tothe type bar as compared to that applied thereto in the second portion of its movement for. downward stroke, where power being unnecessary, is sacrificed to speed. y

The connections proposed by my invenle and inexpensive, mayv be readily ande eaply manufactured, and easily andv quickly assembled, and in addition 4to minimizing y, the number of necessary parts, my invention in providing for the direct connection of the keys lever with the type bar by virtue of the single sublever, promotes great strength and durability and avoids the necessity of adjustment and careful fitting of the parts. I claim 9 1. In a typewriter, a type bar supported adjacentto one end an teeth at its pivoted end forming a gear surivotally having y face along a line eccentric with respect to the said pivot, a sub-lever pivotally mounted at its lower end and having an angular outstanding arm adjacent to its pivoted end, and a rack at its upper end engaging the teeth of the type bar, and a key lever fulorumed intermediate its ends and having at its rear end a laterally projecting roller engaging the lower face of the angular arm of the sub-Jever, as described.

2. In a typewriter, a type bar pivotally supportedadjacent to one end and having at its pivoted end teeth arranged to form a gear eccentric with respect to the pivot thereof, a sub-lever pivotally mounted at its lower end and having a. downwardly acying surface at oneside of its pivot7 said sus lever having a rack lforrnedupon its upper end and engaging the teeth of the type bar, e

and a key lever fulcrumed intermediate its endsiand having means4 movably engaging the said lower surface of the sub-leverl for swinging the level,` when the key lever is actuated.
